Flexible Bouncing Ball for cat

thingiverse

Here's a fun bouncing toy that's perfect for your feline friends or canine companions - depending on the size you decide to print. For cats, I'd suggest going with a diameter of 30-35mm so they can easily grasp and catch the ball using their sharp claws and teeth, thanks to its clever hole design. I like to print mine out in Ninjaflex or Filaflex for a fun and durable finish.
